Yeah. Superman and Batman are in a league entirely of their own. They have truly transcended the genre. They are so far above A-List. I'd consider the A-Listers:

Robin
Spider-Man
Wonder Woman
Whoever happens to be big at the moment.

The A-list is actually:

Batman
Spider-Man
Superman
Hot Names of the moment.

When Wonder Woman gets a motion picture trilogy, or even a movie, call me. Until then, she's not on that level of fame. Anyone who says so is coming at it from a total DC bias (which I guess I should expect on a Justice League board.)
